板栗的雌花减少是由于土壤中速效磷含量低而造成的。通过增施磷肥,提高土壤中速效磷含量和板栗树体内磷素;合理修剪,除去雄花枝、纤细枝、密蔽枝等,减少无益消耗,可达到增加板栗雌花、减少雄花、提高产量的目的。此项技术适合于土壤缺磷 Chestnut female flower is reduced due to the availability of low-available phosphorus in the soil caused. Through the application of phosphate fertilizer, the content of available phosphorus in soil and phosphorus in chestnut trees can be increased; the pruning and removing of male flowering branches, slender branches and shrubs can reduce the unnecessary consumption, increase the female flowers of chestnut, reduce the male flowers and increase the yield . This technology is suitable for soil phosphorus deficiency
